Fix for _on_card_deselected for touch screens.

[peteristhegreat]

Don't emit card_clicked, unless it was the card pressed in the first place. Helps for touch screens.

Hey @peteristhegreat
Great change, thanks for the contribution. When testing I noticed this helps with a mouse as well by preventing deselect event if you mouse down off the card and then mouse up over the card. Which I think is better behavior. Probably the same thing you noticed with a touchscreen.

Thanks!

BTW, this is my project in progress using the library:

https://peteristhegreat.itch.io/five-crowns (It's still in beta but works pretty well)

I should probably just move this to another discussion or thread or fork, but a few other features I got working that might be useful in some examples for other people:

• hand layouts for other players around the edge of the screen (seat anchors) especially in a responsive layout (mobile landscape or vertical or desktop).
